Abstract: Provided are a data receiving device and a corresponding method for receiving the data. The data receiving device comprises a path control logic configured to store L symbol paths, where L is a natural number equal to or greater than 2, L feedback filters configured to calculate L inter-symbol interferences (ISI) for the L symbol paths, respectively, L operators configured to remove the L inter-symbol interferences from an output of a feed-forward equalizer, and a path metric calculator configured to receive outputs of the L operators and calculate a path metric for each of the L symbol paths, wherein the path control logic is configured to select L values among the calculated path metrics for the L symbol paths to update the L symbol paths.

Abstract: An electronic circuit converts a receive signal being analog into reception data being digital. The electronic circuit includes a delay circuit that receives a first receive signal and outputs a reference signal, the reference signal being generated by delaying the first receive signal as much as one of a plurality of different timing delays respectively set to a plurality of loops, a sampler that receives a second receive signal and samples the second receive signal based on the reference signal in each of the plurality of loops, a timing skew estimation circuit that outputs a compensation signal for compensating for a timing skew by extracting a statistical characteristic of a plurality of sample data sampled through the sampler and estimating the timing skew based on the statistical characteristic, and a controller that controls an operation of the timing skew estimation circuit.

Abstract: A data transmission method for transmitting a data signal using four data signal levels during a unit interval and transmitting a data bus inversion (DBI) signal using two DBI signal levels during the unit interval, the method including: receiving n (n is a natural number) data, each of the n data including a first bit and a second bit; counting the number of data in which the first bit and the second bit have the same value among the n data; in response to the counting result being less than or equal to a predetermined number, transmitting the n data using the four data signal levels, together with a DBI signal having a first DBI signal level; and in response to the counting result being greater than the predetermined number, transmitting data, which is obtained by changing a value of either of the first bit and the second bit of the n data, using the four data signal levels, together with a DBI signal having a second DBI signal level different from the first DBI signal level.
